Description

Technical Field

[0001] The present invention relates to the technical field of plasma cutting processing, and in particular to a plasma cutting device for processing stainless steel plates. Background Art

[0002] Plasma arc cutting is a processing method that uses the heat of a high-temperature plasma arc to locally melt (and evaporate) the metal at the workpiece incision, and uses the momentum of high-speed plasma to expel the molten metal to form an incision. Plasma cutting can be used with different working gases to cut various metals that are difficult to cut with oxygen cutting, especially for non-ferrous metals (stainless steel, aluminum, copper, titanium, nickel). Its main advantage is that when cutting metals with light thickness, the plasma cutting speed is fast. The distance between the plasma cutting head and the cutting plate has a great influence on the cutting effect. In the existing technology, when cutting stainless steel plates, most of the stainless steel plates are placed directly on the cutting table for cutting, and the stainless steel plates are not fixed, which causes the stainless steel plates to move easily during cutting, resulting in inaccurate cutting positions.
